Hello.

I have a desktop monitor that uses a DVI cable to connect to my desktop. Earlier today, I had to plug my desktop montior into my laptop with a broken display in order to get some files from my old computer. I had to use a VGA cable.
After I was finished, I unplugged my laptop and plugged the monitor, via DVI cable, back into my desktop. It was working for a couple hours and then the display went dark. My monitor no longer recieves a signal from the desktop.
When I boot the computer, it is able to display up until the start up. After the computer starts, the display no longer works but the computer is still running.
I can boot the comouter using safe mode, but vga mode does not work.

I realize this information is a bit convoluted but is there anyone who would have insight into why this has happened?

Welcome,

Changing display modes [DVI / VGA / DVI] can confuse the monitor. Have you shut down everything, connected the monitor via the DVI cable to the system and then turned on all of the components. A cold boot will usually reset most things to the correct or default position.
